STEAM OR OTHER VALVE.

SPECIFICATION forming part of Letters Patent No. 510,425, dated December12, 1893.

Application filed January 21, 1893. Serial No. 459,284. (No model.)

T or whom it may concern/.-

Be it known that I, FRANK HEDLEY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Steam or other Valves,of which the following is a full, clear, and exact specification.

My invention relates to improvements in steam or other valves and hasfor its object to provide a valve in which one, two or more inlets arecontrolled by a single lever, the parts being of simple construction aswill be hereinafter described.

In the drawings, Figure l is a side elevation of the valve showing theinlets and outlets. Fig. 2isacentral vertical section of the same. Fig.3 is a side elevation of the rocker valve employed for controlling theinlets and outlets, and Fig. 4 is a side elevation of the same, showingmore clearly the diaphragm for separating the inlets. Fig. 5 is a detailview of the head of the valve.

A represents the valve proper; B the rocker valve employed forcontrolling the inlets and outlets; O the valve stem, and D the leverfor operating the same.

As will be seen the shell or casing of the valve A is constructed withsuitable inlet ports a and outlet ports b, one end 0 of the valve beingcast integral with the casing, the other end (1 being removable, toenable the various parts to be inserted and adjusted.

The rocker valve is provided with a central squared opening e to admitof its adjustment on the stem 0, and to prevent said rocker valve fromturning independently of said stem. The rocker valve is also providedwith a circumferential diaphragm g at its center, the said diaphragmhaving a packing ring g, forming two complete and distinct compartments,and also serving to separate the two inlets a and outlets b from eachother. A hearing it is formed in the end 0 of the valve to receive theend of the stem 0, and a recessed bearingi is formed in the end d of thevalve, in which end is journaled the opposite end of the valve stem. Acollar or disk j is provided on the stem and adapted to fit into saidrecess 1' to prevent leakage of steam or liquid at this point, thusdispensing with the ordinary packing which would be otherwise required.The outer end of the stem 0 is squared as at k to receive a lever D forcontrolling the valve B. The end d is provided with a screw thread whichadmits of adjustment tothe parts as theybecome Worn.

I do not wish to limit myself to the use of one diaphragm for separatingthe inlets, and dividing the valves into two compartments, as it isobvious that any number of diaphragms may be employed.

The operation is as follows: When the valve stands in the position shownin Fig. 2 the inlet and outlet ports are separated and closed, thuspreventing entrance to and discharge from the valve. When the valvestands in the position shown in Fig. 6, and the lever is at an angle ofabout forty-five degrees, the rocker valve B will rest at a pointbetween one of the inlet and outlet ports, when steam or liquid will beadmitted to the valve through the ports a and discharged through theports b.

Having now described my invention, I declare that what I claim is- Avalve constructed of a suitable casing provided with two or more inletand outlet ports, said inlet ports being opposite each other one end ofthe casing being cast integral therewith and the other end beingremovable therefrom, said ends being provided with suitable bearings toreceive the ends of the valve stem, the said stem being squared betweensaid hearings to correspond with the squared longitudinal openingin therotating valve, the said valve being provided with one or morediaphragms or disks for dividing the valve proper into two or moreseparate and distinct compartments, substantially as set forth andillustrated.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of January, 1893. 1
